Gravity Solar System

What is gravity?

• The force that keeps planets in orbit around the sun

• The force that causes objects with mass to attract one another

• The energy that is emitted by the sun

• The process by which plants make food using sunlight

What does the Law of Universal Gravitation state?

• Every object in the universe repels every other object.

• The force between two objects is only affected by the distance between them, not by their masses.

• Every object in the universe attracts every other object, and the force is affected by mass and distance.

• The force of gravity between two objects is strongest when they are furthest apart.

What does the Law of Universal Gravitation state about the force between objects?

• The force is only affected by the mass of the objects.

• The force is only affected by the distance between the objects.

• The force is affected by both the mass of the objects and the distance between them.

• The force is not affected by either the mass of the objects or the distance between them.

Develop a model to describe the role of gravity in the motion of planets within the Solar System. Include the Sun and at least two planets in your model.

• A model showing planets moving in straight lines away from the Sun.

• A model showing planets orbiting the Sun in elliptical paths due to gravitational pull.

• A model showing planets stationary in space.

• A model showing planets moving randomly in space.
